In order to ensure rifle barrels have the features of high strength, durability, and light weight, the strength analysis of the barrels under hot temperatures and pressures is very important in the design. A finite element model incorporating the plastic deformation of a typical 0.50 caliber rifle barrel is constructed to determine the stresses caused by the mechanical loads and plastic deformation. According to the simulation results, the finite element analysis is proved to be a power analysis tool for future failure analysis of firearm barrels. The method provides a power tool for analysis of firearm barrels. The projectile was accelerated to 941.7 m/s in 1.430 ms with a pressure profile that reached a maximum of 469.3 MPa. Stresses as large as 1,410 MPa along the interior of the barrel were found where the leading edge of the projectile slides along the bore, but the largest stresses at the exterior of the barrel were found where the barrel wall is thinnest near the chamber.

The Impact

A 1:1 flexible rock shed made of flexible nets and steel-vaulted structure is manufactured and tested for functional evaluation with impact experiment previously. To further discuss the performance of this structure under the impact of rockfalls and to improve the design, numerical simulation for this structure is carried out in this paper. Firstly, the simplified numerical models for characterizing the mechanical behavior of the ring nets and wire meshes are deduced. Then, a detailed finite element model for the flexible rock shed is developed for impact analysis. By comparing the experimental data, the numerical model for the flexible rock shed is shown to be reliable in predicting the dynamic behavior of the flexible rock shed. Finally, combined with the numerical simulation results and experimental results, an improved design is presented, and the numerical simulation results show that the energy dispersion in the improved design of the rock shed is more equalized, and damages on the steel-vaulted structure are much improved.

In this paper, the finite element analysis is made to the modal analysis of the impeller, a finite element model of a impeller with cracks was established. This paper presents results of the modal of the compressor blade subjected to centrifugal force and aerodynamic equilibrium pressure. In this analysis, the numerical models without defects and also with cracks were defined. The simulation results showed that the centrifugal force due to rotational speed can greatly influence the frequency of the impeller. The distribution of two cracked blades effect the natural frequence of the impeller. When two cracked blades locate in the interval position, the increasing value of frequence is maximum. When the two cracked blades interval 150°, the increasing value of frequence is minimum. It provides a basis for modal calculation of the impeller.
